ADJUSTMENTS

The control should be re-calibrated if your reading is not within 20 degrees of the dial setting (350°F). If calibration is

required, the additional steps to be taken are these:

4. Insert a at screwdriver through the center of the thermostat stem and then turn the adjustment screw clockwise to

decrease the oven temperature and counterclockwise to increase the oven temperature. Do not allow the stem to turn.

Turn the adjustment screw only 5 degrees of rotation in the appropriate direction, then repeat Steps 2 and 3 to check

the temperature. Repeat until the temperature is within 10 degrees of 350°F.

5. Set the oven thermostat to 400°F. Check oven temperature again, as instructed in Steps 2 and 3. If the oven

temperature is not within 20 degrees of the dial setting (400°F) it means that the sensing element is inoperative and

the control should be replaced.

ADJUSTMENT OF THERMOSTATIC GRIDDLE BYPASS FLAME LEVEL

When the griddle reaches the temperature at which the dial is set, the control cuts down the ow of gas to the amount

required to keep the griddle at that temperature. Always, however, the control must bypass enough gas to keep the entire

burner lit. To maintain this minimum ame, the bypass must be set carefully and accurately, as follows (see Figure 11).

1. Light the burner, then turn dial FULL ON.

2. After 5 minutes, turn dial clockwise to point slightly beyond rst mark on dial.

3. Remove dial and bezel.

4. With a screwdriver, turn Bypass Adjuster (counterclockwise to increase the ame, clockwise to decrease it) until there

is a minimum ame over the entire burner.

5. Replace bezel and dial, turning the dial clockwise until it locks in the OFF position.

CALIBRATION OF THERMOSTATIC GRIDDLE THERMOSTAT

The griddle temperature control is carefully calibrated at the factory—that is, it is so adjusted that dial settings match ac-

tual temperatures. Field recalibration is seldom necessary, and should not be resorted to unless considerable experience

with cooking results denitely proves that the control is not maintaining the temperatures to which the dial is set.

Recalibration should not be undertaken, however, until the griddle bypass ame has been adjusted (see previous subsec-

tion).

To check temperatures when recalibrating, use a test instrument with a DISC type thermocouple for surface temperature

checking. Drop a couple of drops of oil on griddle surface plate and place thermocouple disc at into the oil.

Proceed as follows (see Figure 11):

1. Remove dial and push out metal insert.

2. Replace dial, turn to 350°F (175°C) mark, and light burner.

3. After burner has been on about 15 minutes check temperature.

4. Continue to check temperature, at 5-minute intervals, until two successive readings are within 5°F (3°C) of each other.

The control should be re-calibrated if your reading is not within 20°F (11°C) of the dial setting (350°F or 175°C). If calibra-

tion is required, the additional steps to be taken are these:

5. Hold dial rmly, insert screwdriver through center of dial, and push calibration stem inward.

DO NOT TURN THIS STEM.

6. While holding calibration stem in rmly with screwdriver, turn dial until it is set at the actual oven temperature as shown

by your test instrument. Release pressure on calibration stem. Replace dial insert.

7. Set dial at 400°F (205°C) mark. Check temperature again, as instructed in steps 3 and 4. If the temperature is not

within 20°F (11°C) of the dial setting (400°F or 205°C), it means that the sensing element is inoperative and the

control should be replaced.
